Abstract
We present a microscopic model to describe the generation of unpolariz ed entangled pair photons from nonlinear crystals. A complete quantum- mechanical calculation of second-order nonlinear susceptibilities (chi ((2))) is presented. The localizability property of single photons is then discussed within the framework of the model.
